Biodegradable materials containing regenerated raw materials and methods for producing same (Biodegradable material containing regenerative raw material and method of producing the same)

摘要

The present invention relates to a biodegradable material comprising a matrix of latex, starch and polybutahydroxybutyrate and / or cellulose powder. This base matrix may contain vegetable fillers such as granules of grain particles or fibers of fibrous plants to form a composite material. The present invention also relates to a process for the production of biodegradable materials, characterized in that all starting materials and rubbers are in particular ground. These ground, for example, substantially ground granulated starting materials are mixed and plasticized in a screw extruder or injection molding machine. The plasticized material can be directly injected into a mold or extruded in a strand form to be processed into granules to be used as an injection molding material.
